Marriott App and Website Errors

I have been unable to use the Marriott App since roughly New Years Day. I've uninstalled and reinstalled several times and actually installed it on a new device yesterday but still get the error. When I log into My reservations I get an error saying "This service is temporarily unavailable. But don't worry. We're on it. Please try again later". I have called their customer service number and they say that nothing is wrong.

The other stranger thing is that when I go online to my account and click on upcoming trips, it says "We're temporarily unable to display the information you requested".

I have seen several comments in the past about the app error and never found a solution. Anyone else have this issue and figured out how to fix it? Customer service has been useless.

This is a bummer and I am afraid end of the road for IT help on my end. You seem to be doing everything right. If you have Facebook or Twitter, I would ask Marriott for some IT help. They are usually good at responding.

I've actually called them a couple of times and was told a ticket was put in. I have a Samsung S8. It's on the website and app for me. I can't see upcoming reservations and cannot check in or use the app for anything other than seeing the front screen. The internet support number is 800-932-2198.

I just powered my phone down for international service, and powered up when I landed. Now I cannot log into the APP. One number of my Rewards number is missing, so I cannot log on. This has happened numerous times to me. When I call the 800 number they routinely say they do not support the APP
